    (54) Composition comprising an oxygen radical scavenger and a surfaceactive copolymer


    (57) A composition, comprising an oxygen radical scavenger preferably selected from superoxide dismutase and mannitol and a surface-active copolymer, the surface-active copolymer having the following formula:



            HO(C₂H₄O)b(C₃H₆O)a(C₂H₄O)bH



    wherein a is an integer such that the hydrophobe represented by (C₃H₆O) has a molecular weight of approximately 950 to 4000, and b is an integer such that the hydrophile portion represented by (C₂H₄O) constitutes approximately 50% to 90% by weight of the compound.
